New salts of dyes which are insoluble in water but soluble in solvents and polar aprotic dipolar organic

摘要

The present invention relates to new salts of dyes which are insoluble in water but soluble in solvents and polar aprotic dipolar organic. / p & & p & it is characterized in that they present the following general formula: & br / (see appended drawing in bopi) & br / in which: / p & & p & the cation chromogenic "means a radical of an organic dye or optical brightener containing at least one group of basic ionization; / p & & p & n is an integer, indicating the number of unit box contained in the polymer of the boric acid ester and / p & & p & m is an integer number or inferior equal to n. / p & & p & the invention applies to the dyeing of a large number of supports made of materials polymers.
